I've got this figured out. You know how Spiderman is able to sense danger with spidey senses? Well Driverbro is able to sense impending police ambushes, but his mind is unable to cope with this power and responds instead by tripping bricks.

The rest of the intros go from the 'LCD acid trip' side of the spectrum all the way to being thrown into a nightmare dystopian horror film.. I rather like them. Probably one of the most interesting parts of the game.
